Specification of Letters Patent.

To (1J/Z whom, it may concern.-

Be it known that I, HILLYARD AUGUSTUS STARR, a citizen of the United States, residing at East Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Stove-Top Member, of which the following is a specification.

This invention relates to improvements in stove lids or covers and center pieces or bridges.

One of the principal objects is to provide an exceedingly simple structure that is not liable to become warped from the heat of' the iire, and is so constructed that air is employed as a cooling medium, said air moreover icing distributed to the iire in order to secure a higher temperature with a less eXp enditure of iuel, and eiiect more nearly perfect combustion resulting in less smoke and less liabilityof clogging-the liues with soot.

A further and important object is to produce a\ lifter-receiving socket that will properly receive an ordinary lifter, is not as liable to wear or break out as the ordinary cast socket, and will not become clogged or filled with dirt.

A still further object is to provide a struc ture that can be readilymolded and cast with rapidity and by inexperienced workmen, moreover eliminating many objectionsv incident to the manufacture of the ordinary stove members, and lessening the liability of defective castings.

In the drawings Figure 1 is a bottom plan view of a center piece or bridge, constructed in accordance with the present invention. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1. Fig. 4 is a cross sectional view on the line 4 4 of Fig. 1. Fig. 5 is a bottom plan view of an embodiment of the invention 1n a stove li'd or cover. Fig. 6 is a detail sectional view on the line 6-6 of Fig. 5. Fig. 7 is a detail perspective view of the socket member, and Fig. 8 is a plan view of the blank of said socket member.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

Referring iirst to the member illustrated in Figs. 1 to 4 inclusive, the cross piece or bridge is of substantially the ordinary shape, and comprises a body having a flat wall 9, provided with marginal depending ribs l0. EX-

tending longitudinally of and depending from the under face of the wall 9 are spaced strengthening ribs 1 1, forming between them a channel 12, having a closed top and an open bottom. The ribs 11 extend from one of the end ribs 10, and terminate short of the oppo* site marginal rib. A depression 13 is formed in the upper side ofthe member, and the Wall 14 thereof is connected to said opposite marginal flange 10 by a web 15. The depression 13 is disposed in alinement with the channel 12. A lifter-receiving socket is formed between said depression and channel. In constructing the said socket, a sheet metal member is employed, comprising an inner casing or lining section 16, and an outer casing section 17. The inner section 16 consists of angularly disposed inclosing walls 18, and

vhas open ends, one end of the section being preferably beveled, as shown at 19.

The outer section 17 also consists of angularly disposed walls 2() that extend partially around the inner section in spaced relation thereto. The two sections are connected by an end wall or web 21.

The socket member, as will be clear by reference to Figs. -2 and 3, is embedded directly in the body, and in the material that is inter osed between the depression 13 and the channel 12. The inner section or lining 16 has its open ends communicating respectively with said depression and channel, and conseqliently an open assageway is formed between the same. T e walls of this passageway are disposed substantially parallel to the upper face of the body wall 9. The outer section 17 constitutes a facin eXtending beneath the inner section, and t e metal of the body ills the space between the two sections. A transverse'rib 22 may be located across the channel 12 in line with the inner open end of the inner section 16 of the socket member, said rib being of less width, however, than the ribs 11. The rib 22 is not essential to the structure, however, and may be dispensed with, its particular function being to cut off a view of the iire through the socket.

There are very great advantages for the structure, as disclosed. The spaced ribs 11 constitute -reinforcements for the stove member, and furthermore constitute an air distributing or conducting channel, the ai-r being supplied through the depression 13 and the socket.

This air serves to maintain the 11o central portion of the member in comparatively cool condition, and at the same time,

supplies oxygen to the ire above the same, and at the line where the smoke begins to leave the liames. As a result, a hotter fire is secured with less 'fuel than is ordinarily required, and furthermore, the combustion being more nearly perfect, the ilues do not become clogged with soot nearly so soon as with the old style solid members.

By means of the casing member employed, an exceedingly sim le, practical and durable lifter socket is prodp properly receive the ordinary lifter, but permits the employment of a number of devices without danger of breaking out or injuring the walls, the casting being reinforced and protected by the sheet metal. One of the most important advantages, however, resides in the ease and cheapness of manufac ture. This structure can be molded in a machine and upon match plate patterns, permitting the employment of inexperienced workmen, who can produce the molds with great rapidity. This will be evident when it is considered that the necessity of drawing separate patterns and handling the 'follow boards, is dispensed with. The socket members are constructed of sheet metal, as shown in Figs. 7 and 8, and the inner section is iilled with core material, so that the metal iows entirely about the same, and the socket is formed with a sheet Ametal lining. Moreover, in this structure, the danger of im erfeet castings is materially reduced. Tith the ordinary closed socket, a comparatively largepercentage of the castings are im erifect from what is known in the art as b owing in the lifter socket. This is caused by the Aaccumulation of steam, which cannot escape, and prevents the proper ilow of the molten metal. In the present structure, however, the core, forming the socket, constitutes a porous line of communication between the sand below the casting and the sand above the same, permitting the esca e of steam therethrou h, and preventing tlie formation of blow-hesin the bottom of the lifter socket. No claim is of course made in the present application to the method of manufacturing the members, as such method will form the subject-matter of another application.

The same structure, with all the resultant advantages can be likewise produced in a stove lid or cover, and attention is invited to Figs` 5 and 6, which illustrate' the same. The body 9a of the cover is provided with peripheral de ending ilanges 10a and with transverse anges 1l, Jforming a branched channel 12a, the latter having a closed top and an o en bottom.. The usual depression is forme in the upper side of the body 9a, the bottom wall thereof being shown at 14a. The socket .member constitutes the means of uced, which will not only com'rr'iunication between the depression and channel, and as this socket member is eX- actly the same structure and is disposed in exactly the same way as that already described, the same reference numerals have been applied thereto. It will be clear that the same advantages are secured. with the cover as with the center piece or bridge, and consequently the invention is clearly appli cable to both members of a stove top.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention, will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any oi: the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is z-F 1. A. stove member comprising a body having spaced depending integral ribs on its under side and between its edges, said ribs forming a channel between them that has a closed top and an open bottom throughout its length, and an open ended lifter-receiving socket formed through the body, the inner end of the socket communicating with the channel between the ribs.
